I think there is a strong selection bias there as well, there's significant research showing how girls and boys are treated differently when getting into "dangerous" situations. It's been my experience as a father of 2 girls that they also love to climb on the outside of playground structures. However what I see with a lot of the parents of other girls (compared to boys) is that they caution the girls a lot more and then they say my girls are so self-confident and "brave". That is not to say that there is no difference between girls and boys, but you there are also huge variations between individuals as well, the way my two daughters are in their "wildness" is so different you would not guess they are siblings.
